Java包裝作爲守護

我用這YAJSW在我的Centos 5.5的機器上運行的Java後臺程序。認爲它運行良好，但出於突發性，我注意到我得到這種錯誤，然後它只是下降。任何幫助我必須做什麼來避免這種問題？一旦出現問題，我可以使用一些監控工具來監控和恢復它嗎？Java包裝作爲守護

下面就是錯誤列表的一部分。

你可以看看：here - 這可能是一個資源泄漏。

問題不在於有太多的文件打開更多的，因爲我已經增加文件描述符。它只是停下來，沒有任何好的線索，如果你看看上面提到的日誌文件，原因是什麼？ – user837306

如果它是資源泄漏它是什麼原因以及如何追蹤它？ – user837306

您可以跟蹤一下linux的過程是通過附加一個strace給它做。

如果是YAJSW本身就是一個問題，如果你正在尋找一個簡單的包裝，讓您的工作和運行，它可以用一個簡單的bash腳本來完成。

until myjob; do 
    echo "restarting myjob" 
    sleep 10 
done

1號線是一個阻塞調用只要myjob正在運行，如果它具有比0以外的任何退出的話，它會重新啓動。

問題是現在我沒有看到從我的應用程序中指出任何問題，因爲如果它會顯示一些線索。由於缺省退出代碼規則，我只是說這個INFO | wrapper | 11-09-19 20：22：13 |重新啓動過程。那麼你建議的腳本是一個shell腳本運行嗎？如何運行？所以你問它睡10ms是嗎？問題是我的應用程序需要繼續運行，因爲它不斷接收數據。 – user837306

這是一個bash腳本，它睡了10秒。如果你需要一個連續的線程爲什麼不在java本身啓動一個新的線程？太多的問題...你嘗試過無咖啡因嗎？ – RHT

什麼是decaf軟件呢？ – user837306

我遇到了在Windows非常相似包裝的日誌輸出。就我而言，多個應用程序正在運行yajsw實例。看起來在某些情況下，yajsw監控Java應用程序的自動端口選擇無法正常工作。

在發生故障的yajsw例如，添加

wrapper.port = 24572

修復該問題。修改wrapper.conf後重新創建服務。我只需要將它添加到失敗的yajsw實例中;其他實例成功自動選擇端口。端口號無關緊要，只需選擇一個未使用的端口即可。
